MIVOC Service

Introduction: MIVOC is a simple method to produce metal ion beams. In this method a volatile chemical compound  including the element of interest and having a sufficient saturated vapour pressure at room temperature is placed into a vacuum chamber (for example Fe(C₅H₅)₂). The chamber is connected to the ion source and the material is let to flow into the plasma through a dozing valve. The molecule breaks down, its components will be ionised and extracted as an ion beam. More information about the MIVOC method at JYFL and relevant publications are presented here. The compounds are commercially available but only with the natural isotopic abundance. For example the afore-mentioned compound has natural Fe abundance as follows:  ⁵⁶Fe (91.75 %), ⁵⁴Fe (5.84 %) and ⁵⁷Fe (2.12 %). The extracted ion beams will have the same intensity ratios. In order to increase the intensity of rare isotope we have to use enriched MIVOC compound. Unfortunately, they are not commercially available.

MIVOC service and available enriched MIVOC beams: The IPHC-CNRS team is able to synthesise several MIVOC compounds using enriched isotopes. This expertise is available as a service which is based on a separate mutual agreement.  Following enriched MIVOC compounds are presently available:

Cr(C₂H₂)₂                                          Safety Data Sheet                    

Fe(C₅H₅)2                                         Safety Data Sheet

Ni(C₅H₅)₂

Hazard statements are presented here.
